Struct BytesDeque 

pub struct BytesDeque(/* private fields */);

VecDeque<Bytes> but slightly more efficient.

Implementations

impl BytesDeque

pub fn new() -> BytesDeque

Empty deque.

pub fn copy_from_slice(bytes: &[u8]) -> BytesDeque

Create a deque by copying from bytes slice.

pub fn len(&self) -> usize

Length in bytes.

pub fn extend(&mut self, bytes: Bytes)

Append Bytes to this deque.

pub fn get_bytes(&self) -> Bytes

Get deque contents as Bytes object.

This operation is cheap if this deque contains only single Bytes object, otherwise it allocates memory and copies data.

pub fn into_bytes(self) -> Bytes

Convert contents into Bytes object.

This function tries to avoid memory allocation when possible.

Trait Implementations

impl Buf for BytesDeque

fn remaining(&self) -> usize

Returns the number of bytes between the current position and the end of the buffer.

fn bytes(&self) -> &[u8]

Returns a slice starting at the current position and of length between 0 and Buf::remaining(). Note that this can return shorter slice (this allows non-continuous internal representation).

fn bytes_vectored<'a>(&'a self, dst: &mut [IoSlice<'a>]) -> usize

Fills dst with potentially multiple slices starting at self’s current position.

fn advance(&mut self, cnt: usize)

Advance the internal cursor of the Buf

fn has_remaining(&self) -> bool

Returns true if there are any more bytes to consume

fn copy_to_slice(&mut self, dst: &mut [u8])

Copies bytes from self into dst.

fn default() -> BytesDeque

Returns the “default value” for a type.

fn from(s: &'a str) -> Self

Converts to this type from the input type.

impl From<Bytes> for BytesDeque

fn from(b: Bytes) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for BytesDeque

fn eq(&self, other: &[u8]) -> bool

Tests for self and other values to be equal, and is used by ==.
